Hydroxyproline index as a tool for nutrition status surveys in malarial regions.

1. The efficiency of the urinary hydroxyproline index as an indicator of nutrition status in mass surveys was investigated. The index was determined in 364 children aged under 5 years who participated in the National Nutrition Status Survey of the Republic of Zambia. The results of these biochemical investigations are given for all children and also according to the presence of various tropical parasitic diseases. 2. In rural areas of Zambia the hydroxyproline index was not related to the age of the child during the first 5 years of life. A lower nutritional status as defined by weight-for-age was associated with a lower hydroxyproline index. 3. The main factor affecting the index was the presence of malaria parasites in the blood. Malaria was associated with a lower index in all circumstances investigated, including children with definite growth failure. The mean of the index for healthy children was 2-49. 4. It is concluded that the index is of value in surveys but only in addition to other assessments of nutritional status. In regions where malaria is endemic the index may be of little value in determining nutritional status unless the presence of malaria parasites in the blood is investigated in all subjects and interpretation of the hydroxyproline index where malaria is confirmed is very complex.

Wastage of edible food in the home: a preliminary study.

The potentially edible food which was wasted in 52 well-motivated households in and around London was collected and analysed. It contained 5 per cent of the food (and rather more of the fat) estimated to have been used during the week, although wide variations were found. Significant amounts of food were also given to animals and birds in some homes, but, when averaged over the whole sample, this only increased the wastage to 6 per cent. Wastage appeared to be related to household size with each person contributing, in effect, about 400 kJ (95 kcal) per day.

The prevalence of hookworm and of S. haematobium in rural Zambia.

The prevalence of hookworm and of S. haematobium in a representative sample of the rural population of seven provinces of Zambia was assessed during a National Nutrition Status Survey. A total of 7212 people of all age and sex groups were examined for hookworm, of whom 4920 (68%) provided a stool sample and of these 48.6% were positive. Regional figures ranged between 11.4% and 77.1%. No differentiation between species of hookworm was attempted nor was it possible to assess the worm load of the individuals surveyed. Hookworm is highly endemic within the rural areas and this is discussed in relation to its known effects on the general health of the population studied during the survey, and the impact of hookworm infestation on morbidity.
